"I got him!"
This was the last one i did a proper cycles render on. For all the future ones i just made the rendered blender viewport full-screen and put the viewport samples upto 1k & had on the optix de-noise thing. Takes like 5 mins rather than 40 :O
Also uploaded the sketch, as with all of these i had an idea of what i wanted to do, but with these sketches i just grabbed random photos and distorted/blurred/rotated/warped them beyond recognition and played with layer blending modes. Then tried to see what was in the chaos.
Its a fun process, and in this one the sketch gave me the idea for the soldier coming in from off screen.
